测距仪周期误差主要是因为（）干扰而产生的。A、机内同频串扰信号B、机内不同频串扰信号

About a year ago, a couple with three children moved into the apartment next door to me.

I never heard any noise from the children, but I often heard the parents shouting at the kids, not in a nice voice, but in a terrible one.

小题1:_______________. I always greeted them, but the only answer I ever got was a “hello” from the eight-year-old girl. 小题2:__________________. One day, when I returned from the hospital, the family were just leaving their apartment and the little girl was holding the outside gate open for the others. I remained in the car doing something unnecessary because I didn’t want to be snubbed(冷落、怠慢)again. When I finally got out of my car and walked towards the gate, the parents were telling the little girl to hurry and get in the car. 小题3:_________________. I hurried though I was still in pain from my leg.

Later that day I wrote a note saying how much her act of kindness had touched an old man’s heart.

The next day the family came over. 小题4:__________________. Her parents thanked me as well.

Now when we meet in the hall, we always greet each other, in a friendly way.

Last night there was a heavy snow. 小题5:_________________. I looked out of the window, thinking what I could do. To my great surprise, there was no snow on my car at all! I was even more surprised to see the lovely girl standing by the gate with an old broom.

Isn’t it amazing that the little kind act of an eight-year-old girl can change so many things for the better?
